Calculate distance how close two strings are.Byclose, it calculates how many operations to transform First to Second The return value is [0-MaxLengthString(First, Second)] 0 means it's identical, Max means it's completely different
static int32 GetStringDistance ( const [FString](API\Runtime\Core\Containers\FString) & First, const [FString](API\Runtime\Core\Containers\FString) & Second )
